It is not uncommon to see today as developing countries are expending their industrial economy, the demand for energy in these countries will continue to grow. So, the expansion of renewable energy sources should be the top priority due to replacement of fossil fuels. I would agree with these viable alternatives to be the priority of countries because of less damage to environment than the nonrenewable ones.
To begin with, as the developing countries are widening the economy and industry sectors, they need more fossil fuels as well. Whereas, chemicals involving increased level of carbon dioxide that are being realized from industries or vehicles, are causing environmental issues which are global warming and negative effect to ozone layer. So, people need to learn how to use fuel efficiently, otherwise, constant use can lead to run out of fuel. As a solution to this problem, replacing the fuels with renewable sources may decrease the amount if the subsidy for implementing the solar panels, wind , geothermal energy plants are covered.
In come developed countries are passing to use the alternatives in order to cause damage less. For example, in the posted article about the great plans of USA in 2010, the president of the country married the nuclear power with wind , sun and clear coal to reach the plans till 2035 in order to save the natural fuels for electricity in spite of the budget needed. Besides, applying electronic cars to use can also reduce the harm , wind plants should be built in the fields to be the main supply for country .
In conclusion, as it is said that I would agree with the replacement to be prioritized globally by developing countries due to importance for the world as above-mentioned.
